2. Was it really a four-seater?
Among the sorties in my logbook, one in 1969 when the weather was too rubbish to launch gliders, Jackaroo G-APAM, pilot Ralph Jones, passengers John Thorne (who used to own Compton Abbas), Ron Wright (ex RCAF CF-100 nav) and myself flew Upavon - Nympsfield to see if the weather was better there. It wasn't. The other 3 had a pint or two, and I was designated pilot back to Upavon when the cloudbase lifted a bit.
It could carry 4 up (cruise about 65 mph).
